I am trying to speed up my website and found that a lot of third-party plugins are slowing up my site. I use one for twitter, two for face book (share and like). Google Pagespeed throws up a bunch of errors related to these plugins like combine external css, javascript, minimize dns lookups, compression etc.
I don't want to stop using these plugins, as they are useful in getting traffic to my site. I also don't want these plugins to slow down my site. I believe many of the webmasters here use these third party plugins and I would like to know any tips that I can use to speed up my site. I already have two CDN's, one for my main content and one for my images (can't put all of them on one CDN for various reasons).
